Harvesting machine for tuft vegetables

A harvesting machine for vegetables, comprising:

• a bearing structure mounted on rolling means;
• a mowing assembly disposed in the front part of said bearing structure, aligned in a substantially horizontal direction, orthogonal to the advancement direction of said machine;
• a conveying surface consisting of a plurality of combs disposed parallel to each other, able to pick up the material cut downstream said mowing assembly and to convey it to an unloading area disposed on said bearing structure,
• wherein said conveying surface comprises at least a belt loop-wound around rotation means, wherein each of said combs is made of a plurality of mainly longitudinally developed flexible laminar bodies, transversally disposed with respect to said belt, said laminar bodies having an edge on their length fastened to said belt and an opposite free edge provided with a plurality of harvesting teeth;
• and
• wherein said conveying surface is coupled with an auxiliary frame supported by said bearing structure and provided with a driving unit able to move said auxiliary frame to maintain constant the position of said mowing assembly with respect to the material to be cut, according to a morphology of the soil, said driving unit comprising feeler means disposed in contact with the soil able to detect its morphology and actuation means coupled with said bearing structure, mutually connected through a transducer group able to convert the displacement signal detected by said feeler means into an electric control signal for said actuation means.
